Question

9(x - 2) = 7x + 5 a) true for all values of x b) true for one value of x c) true for no values of x

Answer 1

Answer:

(b)

Step-by-step explanation:

9(x - 2) = 7x + 5 ← distribute left side

9x - 18 = 7x + 5 ( subtract 7x from both sides )

2x - 18 = 5 ( add 18 to both sides )

2x = 23 ( divide both sides by 2 )

x = $\frac{23}{2}$

Answer 2

Answer:

b) true for one value

Explanation:

If you solve for x, there is only one value of x
